Fringg 1f0fef114b refactor: complete structlog migration with contextvars, kwargs, and logging hardening
- Add ContextVarsMiddleware for automatic user_id/chat_id/username binding
  via structlog contextvars (aiogram) and http_method/http_path (FastAPI)
- Use bound_contextvars() context manager instead of clear_contextvars()
  to safely restore previous state instead of wiping all context
- Register ContextVarsMiddleware as outermost middleware (before GlobalError)
  so all error logs include user context
- Replace structlog.get_logger() with structlog.get_logger(__name__) across
  270 calls in 265 files for meaningful logger names
- Switch wrapper_class from BoundLogger to make_filtering_bound_logger()
  for pre-processor level filtering (performance optimization)
- Migrate 1411 %-style positional arg logger calls to structlog kwargs
  style across 161 files via AST script
- Migrate log_rotation_service.py from stdlib logging to structlog
- Add payment module prefixes to TelegramNotifierProcessor.IGNORED_LOGGER_PREFIXES
  and ExcludePaymentFilter.PAYMENT_MODULES to prevent payment data leaking
  to Telegram notifications and general log files
- Fix LoggingMiddleware: add from_user null-safety for channel posts,
  switch time.time() to time.monotonic() for duration measurement
- Remove duplicate logger assignments in purchase.py, config.py,
  inline.py, and admin/payments.py
